Merge tag 'staging-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging / IIO driver updates from Greg KH: "Here is the large set of staging and IIO driver updates for 5.10-rc1. Included in here are: - new IIO drivers - new IIO driver frameworks - various IIO driver fixes and updates - IIO device tree conversions to yaml - so many minor staging driver coding style cleanups - most cdev driver moved out of staging - no staging drivers added or removed Full details are in the shortlog. All of these have been in linux-next for a while with no reported issues" * tag 'staging-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (476 commits) staging: comedi: check validity of wMaxPacketSize of usb endpoints found staging: wfx: improve robustness of wfx_get_hw_rate() staging: wfx: drop unicode characters from strings staging: wfx: gpiod_get_value() can return an error staging: wfx: increase robustness of hif_generic_confirm() staging: wfx: wfx_init_common() returns NULL on error staging: wfx: standardize the error when vif does not exist staging: wfx: check memory allocation staging: wfx: improve error handling of hif_join() staging: dpaa2-switch: add a dpaa2_switch prefix to all functions in ethsw.c staging: dpaa2-switch: add a dpaa2_switch_ prefix to all functions in ethsw-ethtool.c staging: rtl8188eu: Fix long lines dt-bindings: staging: wfx: silabs,wfx yaml conversion staging: wfx: update copyrights dates staging: wfx: fix QoS priority for slow buses staging: wfx: fix BA sessions for older firmwares staging: wfx: remove remaining code of 'secure link' feature staging: wfx: fix handling of MMIC error staging: vchiq: Fix list_for_each exit tests staging: greybus: use __force when assigning __u8 value to snd_ctl_elem_type_t ...
